Description

Technical Field

[0001] This invention relates to a push-button valve for bathroom fixture fittings. This push-button valve is particularly useful for controlling the flow rate of water through bathroom fixture fittings. Background Technology

[0002] A push-button valve is a device used in conjunction with water supply plumbing in bathrooms, kitchens, or similar applications. It controls water flow via a button or push-button operation, which activates an internal mechanism that either releases or shuts off the water flow. Push-button valves can be at least partially integrated into bathroom fixtures.

[0003] Push-button valves are known to regulate water temperature or volumetric flow rate when the valve is opened, in addition to releasing or cutting off water flow. However, these push-button valves cannot simultaneously control water temperature and volumetric flow rate. Summary of the Invention

[0004] Therefore, the object of the present invention is to at least partially solve the problems described in conjunction with the prior art, and in particular to provide a push-button valve for bathroom equipment accessories, by means of which water temperature and water volume flow rate can be adjusted.

[0005] This objective is achieved by a press valve according to the features of the independent claim. Other advantageous embodiments of the invention are given in the dependent claims. It should be noted that the features individually listed in the dependent claims can be combined with each other in any technically reasonable manner and define other embodiments of the invention. Furthermore, the features given in the claims are specifically described and set forth in the specification, while other preferred embodiments of the invention are shown.

[0006] A push-button valve for bathroom fixture accessories helps to achieve this purpose, the push-button valve comprising at least: - A valve housing having a cold water inlet for cold water, a hot water inlet for hot water, a mixing chamber for mixing cold water and hot water into a mixed water, and a mixed water outlet for the mixed water, wherein the valve housing extends along the longitudinal axis of the housing; - A valve stem capable of moving parallel to its longitudinal axis between a closed position and an open position, wherein pressing the valve closes it in the closed position and pressing the valve open it in the open position; and - A flow regulating mechanism comprising an inner sleeve and an outer sleeve, wherein the inner sleeve is adjustable relative to the outer sleeve, particularly parallel to the longitudinal axis of the flow regulating mechanism, to regulate the temperature of the mixed water, and wherein the inner sleeve is adjustable relative to the outer sleeve, particularly about a rotation axis, to regulate the volumetric flow rate of the mixed water.

[0007] Press-button valves are particularly suitable for bathroom fixture fittings that allow for the on-demand dispensing of liquids, especially water, in showers, bathtubs, and / or sinks. These fittings can be, for example, concealed inserts. These concealed inserts can be installed in wall openings, wall recesses, or other substrates. Such concealed inserts are particularly suitable for use in lightweight wall systems and pre-installed wall systems.

[0008] Cold and hot water can be supplied to the pressure valve or bathroom fixtures. Cold water can be supplied to the pressure valve or bathroom fixtures, particularly from a cold water source, such as a public water supply network and / or a cold water supply pipe. Hot water can be supplied to the pressure valve or bathroom fixtures, particularly from a hot water source, such as a water heater or a central heating system and / or a hot water supply pipe. The temperature of the cold water is particularly high at 25°C, preferably from 1°C to 25°C, and particularly preferably from 5°C to 20°C. The temperature of the hot water is particularly high at 90°C, preferably from 25°C to 90°C, and particularly preferably from 55°C to 65°C.

[0009] The push-button valve has a valve body. The valve body may be at least partially made of plastic and / or metal, such as brass. The valve body may be at least partially constructed as tubular and / or extend along a longitudinal axis of the body, which is particularly straight. The longitudinal axis of the body may be the central axis of the valve body. The valve body may extend from a first longitudinal end to a second longitudinal end. The length of the valve body (particularly parallel to the longitudinal axis of the body) may be, for example, from 50 mm to 150 mm.

[0010] The valve body has at least one cold water inlet for cold water and at least one hot water inlet for hot water. The cold water inlet and / or hot water inlet may be constructed within the shell wall of the valve body. The cold water inlet and / or hot water inlet may extend radially through the shell wall of the valve body. The cold water inlet and / or hot water inlet are particularly not constructed at any longitudinal end of the valve body. The cold water inlet and / or hot water inlet may be configured as a slit and / or extend circumferentially (particularly around the longitudinal axis of the shell).

[0011] A mixing chamber is formed within the valve body. Cold water can be supplied to the mixing chamber through a cold water inlet, and hot water can be supplied through a hot water inlet. The cold and hot water can mix within the mixing chamber to form a mixed water. The valve body has a mixed water outlet for the mixed water. The mixed water can be output to the surrounding environment of the push-button valve or to bathroom fixtures, in particular, through the mixed water outlet. The mixed water outlet can be located at the first longitudinal end of the valve body and / or the first longitudinal valve end of the push-button valve.

[0012] The push-button valve has a stem extending along a longitudinal axis, which is particularly straight. The longitudinal axis may be the central axis of the stem. The stem may be at least partially made of plastic and / or metal, such as brass. The stem length (particularly parallel to the longitudinal axis) may be, for example, 50 mm to 150 mm, and / or the stem diameter (particularly perpendicular to the longitudinal axis) may be, for example, 5 mm to 20 mm. The longitudinal axis extends particularly parallel to or coaxial with the longitudinal axis of the housing. The stem may extend at least partially through the valve housing and / or at least partially through the mixing chamber. The stem may move parallel to the longitudinal axis between a closed position and an open position, in which the push-button valve is closed and in the open position is opened. In the closed position, the stem may close the mixed water outlet and / or the stem may at least partially extend into the mixed water outlet. In the closed position, the stem may close the mixed water outlet, particularly by passing the first longitudinal end of the stem through a mixed water outlet seal. The mixed water outlet seal may be configured as an O-ring. When in the open position, the valve stem releases the mixed water outlet, allowing the mixed water to flow from the mixing chamber through the mixed water outlet out of the press valve.

[0013] The valve stem can be moved between a closed and an open position by pressing a button on the valve. The button can be located at the second longitudinal valve end of the valve. The button can be pressed or moved by the user of the valve, particularly parallel to the longitudinal axis of the housing and / or parallel to the longitudinal axis of the stem. The valve stem can be moved between the closed and open positions by means of a ballpoint pen mechanism / ballpoint pen pressing mechanism. Such a ballpoint pen mechanism, as a ratchet mechanism, is well known and widely used. A ratchet mechanism is a transmission mechanism or device that can occupy two stable positions and maintain those positions without external force. For example, in a ballpoint pen, the pen tip can be moved by the ballpoint pen mechanism. The button can be connected to the valve stem via a ballpoint pen mechanism or a ratchet mechanism. The ballpoint pen mechanism or ratchet mechanism can be operated by the button. By pressing the button and / or the ballpoint pen mechanism or ratchet mechanism, the valve stem can be moved between the closed and open positions. The ballpoint pen mechanism or ratchet mechanism may include a pressing element and a pushing element, which can move between a first position and a second position in a toothed guide rail, particularly parallel to the longitudinal axis of the housing and / or the longitudinal axis of the stem. As an alternative, the valve stem can be operated using a handle or rotating component.

[0014] The press valve has a flow regulating mechanism. The flow regulating mechanism includes an inner sleeve and an outer sleeve. The inner sleeve and outer sleeve extend particularly along a longitudinal axis that is especially linear. The longitudinal axis of the sleeve may be the central axis of the inner sleeve and / or the outer sleeve. The longitudinal axis of the sleeve may extend parallel to or coaxial with the longitudinal axis of the housing and / or the longitudinal axis of the rod. The inner sleeve and / or the outer sleeve are at least partially constructed as tubular and / or extend coaxially with each other. The inner sleeve is particularly arranged within the outer sleeve. A mixing chamber may be at least partially constructed within the inner sleeve and / or the outer sleeve. The inner sleeve and / or the outer sleeve may at least partially define the mixing chamber. The inner sleeve length (particularly parallel to the sleeve's longitudinal axis) may, for example, be from 10 mm to 60 mm, and / or the outer sleeve length (particularly parallel to the sleeve's longitudinal axis) may, for example, be from 10 mm to 80 mm. The outer sleeve outer diameter (particularly perpendicular to the sleeve's longitudinal axis) may, for example, be from 20 mm to 50 mm. The outer diameter of the outer sleeve can (basically) correspond to the inner diameter of the valve body. The inner diameter of the outer sleeve (especially perpendicular to the longitudinal axis of the sleeve) can, for example, be from 15 mm to 45 mm. The outer diameter of the inner sleeve (especially perpendicular to the longitudinal axis of the sleeve) can (basically) correspond to the inner diameter of the outer sleeve. The inner diameter of the inner sleeve (especially perpendicular to the longitudinal axis of the sleeve) can, for example, be from 5 mm to 40 mm.

[0015] The inner sleeve can move relative to the outer sleeve, particularly parallel to its longitudinal axis, to adjust the temperature of the mixed water. By adjusting the inner sleeve, particularly parallel to its longitudinal axis, the mixing ratio of cold and hot water in the mixing chamber can be adjusted. The inner sleeve can move between a hot water position and a cold water position. Moving the inner sleeve towards the cold water position increases the flow rate of cold water into the mixing chamber and decreases the flow rate of hot water. In the cold water position, the cold water flow rate is at its maximum, and the hot water flow rate is at its minimum, especially zero. In the cold water position, the temperature of the mixed water corresponds to the cold water temperature. Moving the inner sleeve towards the hot water position increases the flow rate of hot water into the mixing chamber and decreases the flow rate of cold water. In the hot water position, the hot water flow rate is at its maximum, and the cold water flow rate is at its minimum, especially zero. In the hot water position, the temperature of the mixed water corresponds to the hot water temperature.

[0016] The inner sleeve can rotate relative to the outer sleeve about a rotation axis to adjust the volumetric flow rate of the mixed water. Particularly when the valve stem is (fully) in the open position and / or the push valve is (fully) open, the inner sleeve can move relative to the outer sleeve about the rotation axis to adjust the volumetric flow rate of the mixed water output through the mixed water outlet. The rotation axis is particularly parallel to or coaxial with the longitudinal axis of the housing, the longitudinal axis of the stem, and / or the longitudinal axis of the sleeve. The inner sleeve can rotate about the rotation axis, particularly between the first and second flow positions, by a rotation angle of, for example, 10° to 90°, preferably 10° to 45°. When the inner sleeve is moved or rotated towards the first flow position, the volumetric flow rate of the mixed water can decrease particularly continuously, and / or when the inner sleeve is moved or rotated towards the second flow position, the volumetric flow rate of the mixed water can increase particularly continuously. At the first flow position, the volumetric flow rate of the mixed water is minimum, and / or at the second flow position, the volumetric flow rate of the mixed water is maximum.

[0017] As an alternative, the inner sleeve can also rotate about the axis of rotation to adjust the temperature of the mixed water, and can move relative to the outer sleeve parallel to the longitudinal axis of the sleeve to adjust the volumetric flow rate of the mixed water.

[0018] The flow regulating mechanism can adjust both the temperature and volumetric flow rate of the mixed water.

[0019] The push-button valve may have a temperature regulating element for adjusting the inner sleeve, particularly parallel to the longitudinal axis of the sleeve. The temperature regulating element can be operated and / or held by the user of the push-button valve. The temperature regulating element may be at least partially constructed as annular, tubular, or sleeve-shaped. The temperature regulating element may be located at the end of the second longitudinal housing and / or the end of the second longitudinal valve. The temperature regulating element may be arranged coaxially with the longitudinal axis of the housing, the longitudinal axis of the rod, the longitudinal axis of the sleeve, and / or the axis of rotation. The temperature regulating element may be connected to the inner sleeve via a transmission element and / or a slider. The transmission element and / or slider may be arranged on the valve stem. The slider may be arranged on the transmission element. The transmission element and / or slider may be arranged coaxially with the valve stem and / or the inner sleeve.

[0020] The temperature regulating component can rotate about its rotation axis. While rotating about its rotation axis, the temperature regulating component can move parallel to the longitudinal axis of the housing, the longitudinal axis of the rod, and / or the longitudinal axis of the sleeve.

[0021] The temperature control element can be constructed as a nut. The temperature control element can be arranged on the external thread of the valve body using internal threads.

[0022] The push-button valve may have a flow regulating element for rotating the inner sleeve, particularly about a rotation axis. The flow regulating element is particularly operable and / or held by the user of the push-button valve. The flow regulating element may be at least partially constructed as annular, tubular, or sleeve-shaped. The flow regulating element may be located at the end of the second longitudinal housing and / or the end of the second longitudinal valve. The flow regulating element may be arranged coaxially with the longitudinal axis of the housing, the longitudinal axis of the rod, the longitudinal axis of the sleeve, and / or the rotation axis. The flow regulating element may be located particularly close to the temperature regulating element. The flow regulating element must not move parallel to the longitudinal axis of the housing, the longitudinal axis of the rod, the longitudinal axis of the sleeve, and / or the rotation axis. The flow regulating element may be connected to the inner sleeve via a connector and / or a transmission element. The connector may be located on the valve stem and / or particularly close to the transmission element. The connector may extend through the wall of the valve housing and / or extend to the flow regulating element.

[0023] The flow regulating component can rotate about its axis of rotation. By rotating the flow regulating component, the inner sleeve can be rotated about its axis of rotation, especially via the connecting parts and / or transmission parts.

[0024] The flow regulator can be connected to the inner sleeve via a coupling structure, allowing the inner sleeve to move relative to the flow regulator parallel to its longitudinal axis. This coupling structure transmits rotational force to the inner sleeve, enabling translational and parallel-to-its-longitudinal-axis movement of the inner sleeve and / or movement between cold and hot water positions. The coupling structure can be constructed between the connector and the transmission component. The coupling structure can be at least partially formed by a first tooth of the transmission component and a second tooth of the connector. The first tooth of the transmission component and the second tooth of the connector can mesh with each other.

[0025] The inner sleeve and / or outer sleeve may be made at least partially of ceramic.

[0026] The outer sleeve may have at least a first cold water opening and at least a first hot water opening, and the inner sleeve may have at least a second cold water opening and at least a second hot water opening. The first cold water opening and the first hot water opening may have a first distance (particularly parallel to the longitudinal axis of the sleeve), and / or the second cold water opening and the second hot water opening may have a second distance (particularly parallel to the longitudinal axis of the sleeve). The first distance may be greater than the second distance. The outer sleeve is arranged in the valve body in such a way that the first cold water opening (particularly in the radial direction) is at least partially aligned with the cold water inlet of the valve body, and / or the first hot water opening (particularly in the radial direction) is at least partially aligned with the hot water inlet of the valve body.

[0027] The second cold water opening and the second hot water opening of the inner sleeve are specifically configured such that, when the inner sleeve moves parallel to the longitudinal axis of the sleeve towards the cold water position, the cross-sectional area for cold water flow between the first cold water opening and the second cold water opening increases, while the cross-sectional area for hot water flow between the first hot water opening and the second hot water opening decreases. The second cold water opening and the second hot water opening of the inner sleeve are specifically configured such that, when the inner sleeve moves parallel to the longitudinal axis of the sleeve towards the hot water position, the cross-sectional area for cold water flow between the first cold water opening and the second cold water opening decreases, while the cross-sectional area for hot water flow between the first hot water opening and the second hot water opening increases.

[0028] The second cold water opening and the second hot water opening of the inner sleeve are specifically configured such that, when the inner sleeve rotates about the rotation axis in the direction of the first flow position, the cross-sectional area for cold water flow between the first cold water opening and the second cold water opening, and the cross-sectional area for hot water flow between the first hot water opening and the second hot water opening, both decrease. Conversely, the second cold water opening and the second hot water opening of the inner sleeve are specifically configured such that, when the inner sleeve rotates about the rotation axis in the direction of the second flow position, the cross-sectional area for cold water flow between the first cold water opening and the second cold water opening, and the cross-sectional area for hot water flow between the first hot water opening and the second hot water opening, both increase.

[0029] The first cold water opening, the first hot water opening, the second cold water opening, and / or the second hot water opening can be configured as slits. The first cold water opening, the first hot water opening, the second cold water opening, and / or the second hot water opening can extend in a circumferential direction around the longitudinal axis of the sleeve.

Detailed Implementation

[0031] Figure 1 A longitudinal cross-sectional view shows a push-button valve 1. The push-button valve 1 includes a valve housing 2, which is tubular and extends along a (straight) longitudinal axis 7. The valve housing 2 has a cold water inlet 3 for cold water and a hot water inlet 4 for hot water. The cold water inlet 3 and the hot water inlet 4 are constructed within the shell wall 24 of the valve housing 2 and extend in a slit-like manner and circumferentially around the longitudinal axis 7. A mixing chamber 6 is constructed within the valve housing 2, through which cold water can be supplied and hot water can be supplied through the hot water inlet 4. The cold water and hot water can mix to form a mixed water within the mixing chamber 6. The valve housing 2 has a mixed water outlet 5 at a first longitudinal valve end 25, through which the mixed water can flow out of the push-button valve 1.

[0032] The push valve 1 has a valve stem 8 that extends along a (straight) longitudinal axis 9 and coaxially with the longitudinal axis 7 of the housing. Figure 1 In the closed position 10, valve stem 8 closes the mixed water outlet 5, preventing mixed water from flowing out of the mixing chamber 6. In the closed position 10, the first longitudinal rod end 27 of valve stem 8 extends through the mixed water outlet seal 29, thereby closing the mixed water outlet 5.

[0033] The first spring 30 presses the second longitudinal rod end 28 of the valve stem 8 against the ballpoint pen mechanism 32. The first spring 30 is tensioned between the mixing chamber inner wall 33 of the mixing chamber 6 and the retaining ring 34, which engages with the rod groove 35 of the valve stem 8. The ballpoint pen mechanism 32 includes a pressing member 36 and a pushing member 37, the pushing member 37 being able to move within the toothed guide rail 38... Figure 1 The first position 39 shown is Figure 2 The pusher 37 can move between the second position 40 shown. By pressing the presser 36, the pusher 37 can move between the first position 39 and the second position 40. The presser 36 is connected to a button (not shown), which allows the presser 36 to be pressed or moved parallel to the longitudinal axis 7 of the housing.

[0034] Figure 2 A push valve 1 is shown, wherein pressing the push member 36 causes the push member 37 to move toward the second longitudinal valve end 26 of the push valve 1. As a result, the valve stem 8, under the action of the first spring 30, moves from... Figure 1The valve stem 8 moves from the closed position 10 to the open position 11 along the longitudinal axis 9 of the stem, so that it no longer passes through the mixed water outlet seal 29, and the mixed water outlet 5 opens. In the open position 11, mixed water can flow out from the mixing chamber 6 through the mixed water outlet 5. Pressing the pressing member 36 again moves the valve stem 8 back to its original position. Figure 1 The closing position is shown as 10.

[0035] The push valve 1 includes a flow regulating mechanism 12 having an inner sleeve 13 and an outer sleeve 14. The outer sleeve 14 has an outer sleeve outer diameter 41, which (generally) corresponds to the inner diameter 42 of the valve housing 2. The inner sleeve 13 is disposed within the outer sleeve 14 and has an inner sleeve outer diameter 43, which (generally) corresponds to the inner diameter 44 of the outer sleeve 14. The inner sleeve 13 is coaxially arranged with the outer sleeve 14 and extends along a (linear) sleeve longitudinal axis 15. A mixing chamber 6 is constructed within the inner sleeve 13. The inner sleeve 13 at least partially defines the mixing chamber 6. The outer sleeve 14 has a first cold water opening 20 for cold water and a first hot water opening 22 for hot water. The first cold water opening 20 (at least partially and / or perpendicular to the longitudinal axis 7 of the housing) is aligned with the cold water inlet 3 of the valve housing 2, allowing cold water to flow into the mixing chamber 6 through the first cold water opening 20. The first hot water opening 22 (at least partially and / or perpendicular to the longitudinal axis 7 of the housing) is aligned with the hot water inlet 4 of the valve housing 2, allowing hot water to flow into the mixing chamber 6 through the first hot water opening 22. The inner sleeve 13 has a second cold water opening 21 for cold water and a second hot water opening 23 for hot water. When the second cold water opening 21 of the inner sleeve 13 (perpendicular to the longitudinal axis 15 of the sleeve) is at least partially aligned with the first cold water opening 20 of the outer sleeve 14, cold water can flow into the mixing chamber 6. When the second hot water opening 23 of the inner sleeve 13 (perpendicular to the longitudinal axis 15 of the sleeve) is at least partially aligned with the first hot water opening 22 of the outer sleeve 14, hot water can flow into the mixing chamber 6.

[0036] Figure 3The push-button valve 1 is shown in a longitudinal cross-sectional view, with the inner sleeve 13 in the hot water position 45. In the hot water position 45, the inner sleeve 13 moves to its maximum extent relative to the outer sleeve 14 towards the second longitudinal valve end 26 of the push-button valve 1. In the hot water position 45, the second hot water opening 23 of the inner sleeve 13 (at least partially) is aligned with the first hot water opening 22 of the outer sleeve 14, allowing hot water to flow into the mixing chamber 6 through the hot water inlet 4 of the valve housing 2 and the hot water openings 22 and 23. In the hot water position 45, the second cold water opening 21 of the inner sleeve 13 is not aligned with the first cold water opening 20 of the outer sleeve 14, preventing cold water from flowing into the mixing chamber 6 through the cold water inlet 3 of the valve housing 2 and the cold water openings 20 and 21. In the hot water position 45, only hot water and no cold water can flow into the mixing chamber 6. Therefore, the temperature of the mixed water in the mixing chamber 6 can reach its maximum, corresponding to the temperature of the hot water. The first cold water opening 20 and the first hot water opening 22 (parallel to the longitudinal axis 15 of the sleeve) have a first distance 51, and the second cold water opening 21 and the second hot water opening 23 (parallel to the longitudinal axis 15 of the sleeve) have a second distance 52, the second distance 52 being smaller than the first distance 51.

[0037] The inner sleeve 13 is connected to the temperature regulating element 17 via a transmission element 47 and a slider 48. The temperature regulating element 17 is constructed as a nut and has an internal thread 49. The temperature regulating element 17 is mounted on the external thread 50 of the valve body 2 via the internal thread 49 and is rotatable about a rotation axis 16. The rotation axis 16 is coaxial with the longitudinal axis 7 of the housing or the longitudinal axis 15 of the sleeve. The temperature regulating element 17 can be rotated about the rotation axis 16 by the user of the press valve 1. By rotating the temperature regulating element 17 about the rotation axis 16, the inner sleeve 13 can be moved relative to the outer sleeve 14 along the sleeve's longitudinal axis 15 via the slider 48 and the transmission element 47. Figure 3 The hot water location shown is 45 and Figure 4 The cold water position 46 shown is movable. Components capable of moving parallel to the longitudinal axis 7 of the housing or the longitudinal axis 15 of the sleeve—temperature regulating element 17, slider 48, transmission element 47, and inner sleeve 13—are... Figure 3 It is marked with a dashed line.

[0038] Figure 4The push-button valve 1 is shown in longitudinal cross-section, wherein the inner sleeve 13 is moved relative to the outer sleeve 14 along the sleeve's longitudinal axis 15 to the cold water position 46 by rotating the temperature regulating element 17 about the rotation axis 16. In the cold water position 46, the inner sleeve 13 is moved to its maximum extent relative to the outer sleeve 14 towards the first longitudinal valve end 25 of the push-button valve 1. In the cold water position 46, the second hot water opening 23 of the inner sleeve 13 is not aligned with the first hot water opening 22 of the outer sleeve 14, preventing hot water from flowing into the mixing chamber 6 through the hot water inlet 4 and the hot water openings 22 and 23 of the valve housing 2. In the cold water position 46, the second cold water opening 21 of the inner sleeve 13 (at least partially) is aligned with the first cold water opening 20 of the outer sleeve 14, allowing cold water to flow into the mixing chamber 6 through the cold water inlet 3 and the cold water openings 20 and 21 of the valve housing 2. In the cold water position 46, only cold water, and no hot water, can flow into the mixing chamber 6. Therefore, the temperature of the mixed water in mixing chamber 6 can be the lowest possible temperature, corresponding to the temperature of cold water. In the cold water position 46, the temperature regulating element 17 moves towards the first longitudinal valve end 25, causing the second spring 31 to tension. If the temperature regulating element 17 is moved towards the second longitudinal valve end 26 by rotating about the rotation axis 16, the second spring 31 will cause the inner sleeve 13, the transmission element 47, and the slider 48 to move until the inner sleeve 13 reaches the desired position again. Figure 3 The hot water location is shown at 45.

[0039] Figure 5 The push valve 1 is shown in longitudinal cross-section, with the inner sleeve 13 in the first flow position 53. The inner sleeve 13 is connected to the flow regulating member 18 via a transmission member 47 and a connector 55. By rotating the flow regulating member 18 about the rotation axis 16, the inner sleeve 13 can be moved relative to the outer sleeve 14 about the rotation axis 16 via the connector 55 and the transmission member 47. Figure 5 The first flow location 53 shown is... Figure 8 The flow rate adjustment element 18 can move or rotate between the second flow rate positions 54 shown. Rotating the flow rate adjustment element 18 about the rotation axis 16 will not cause the flow rate adjustment element 18 and the connecting element 55 to move parallel to the longitudinal axis 7 of the housing or the longitudinal axis 15 of the sleeve.

[0040] Figure 6 A perspective view shows the flow regulating mechanism 12, which has an inner sleeve 13 and an outer sleeve 14. To make the inner sleeve 13 visible, in... Figure 6 The outer sleeve 14 is shown in a partial cross-sectional view. Figure 6 The first cold water inlet 20 and the first hot water inlet 22 of the outer sleeve 14, the second cold water inlet 21 and the second hot water inlet 23 of the inner sleeve 13 can be seen. The inner sleeve 13 is connected to the outer sleeve 14 via the transmission member 47 and the connecting member 55. Figure 5The flow regulating element 18 is shown connected. A coupling structure 19 is constructed between the transmission element 47 and the connecting element 55, the coupling structure 19 enabling the inner sleeve 13 and the transmission element 47 to be relative to the connecting element 55 and... Figure 5 The flow regulating element 18 shown moves parallel to the longitudinal axis 7 of the housing or parallel to the longitudinal axis 15 of the sleeve. Regardless of the position of the inner sleeve 13 along the longitudinal axis 15, the coupling structure 19 allows the inner sleeve 13 to rotate about the rotation axis 16.
